flashing cyttsp4 (Cypress Txx4xx) controller

Hello!
Please tell me how I flash controller touchscreen (Cypress Txx4xx) driver if I compiled from source?
There is a method forced_upgrade, but he does not appear. And I do not direct to flash your controller. Maybe something can be rewritten as the driver that he flashed himself Startup?
Available method manual_upgrade.
